Identification of unknown corpse can be established by their body features and belongings; when the features are distorted, it becomes a challenge for the forensic experts. Orthopantamograph (OPG) analysis is a simple, noninvasive, economic, and reliable method to sort for identification of the unidentified.
The aim of this study was to assess the efficacy of OPG in age and sex determination. The objective of our study was to evaluate various measurements on the mandibular ramus and to correlate them with the age and sex of an individual.
A retrospective study was conducted using 150 OPGs that were taken in the Department of Oral Medicine and Radiology using Orthophos XG3 OPG machine. The mandibular ramus measurements were carried out using WebPlot Digitizer v 4.1. The measurement was statistically assessed.
SPSS version 20 was used for discriminate analysis, correlation, and regression analysis.
The male population showed higher values of ramus measurements compared to the female population. A regression equation was positively drawn to estimate the age of the unknown individual.
Coronoid height is the main predictive factor in age estimation of an individual irrespective of the gender whereas gonial angle is the extrapolative tool in gender prediction.
通过尸体特征和遗物可以识别无名尸体；当尸体特征被扭曲时，这对法医专家来说是一项挑战。全景曲面体层摄影（OPG）分析是一种简单、无创、经济且可靠的用于识别无名尸体的方法。
本研究的目的是评估OPG在年龄和性别判定方面的有效性。我们研究的目标是评估下颌升支的各项测量指标，并将它们与个体的年龄和性别相关联。
采用回顾性研究，使用在口腔医学与放射科用Orthophos XG3 OPG机拍摄的150份OPG影像。使用WebPlot Digitizer v 4.1对下颌升支进行测量。对测量结果进行统计学评估。
使用SPSS 20版进行判别分析、相关性分析和回归分析。
男性群体的升支测量值高于女性群体。绘制了一个回归方程来估计无名个体的年龄。
无论性别如何，喙突高度是个体年龄估计的主要预测因素，而下颌角是性别预测的推断工具。
